JOURNAL-BOX FOR RAILROAD-CARS, 8w.

Specification of Letters Patent No. 18,984, dated December 29, 1857.

To all whom it may concern:

Be it known that I, JAS. A. NORRIS, of Philadelphia, in the county ofPhiladelphia, in the State of Pennsylvania, have invented a new anduseful Improvement in Boxes for Railroad-Car and other Axles; and I dohereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings and to theletters of reference marked thereon.

The nature of my invention consists in certain improvements in boxes forrail road car and other axles as hereinafter described.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation, reference being hadto the accompanying drawings and to the letters of reference thereon.

Figure 1, represents a top view; Fig. 2, a vertical section at (y, yFig. 1; Fig. 3, a vertical section at (00, 00,) Fig. 1 and Fig. 4 an endview of my improved box.

(A) is a cast iron box of the form shown; in the upper part of which isformed a reservoir (C,) for containing oil, or lubricating material, thesame being supplied through an opening (7),) which opening is providedwith a close cover ((1,).

(1),) is the brass box or bearing which is formed as represented,fitting in the upper part of the box (A) and covering the upper half ofthe bearing surface of the journal (13,) which is constructed without acollar (which, is generally formed on similar axles) in order that thebox (D) may be withdrawn through an opening in the back endof the box(A,) which opening is effectually closed by a plate (F,) secured bybolts (7, In the bottom of the oil reservoir (0,) is an oil hole (0,)and immediately under it a similar one (d,) in the brass box (D,),whereby, the shaft (13,) is perfectly lubricated, the waste oil fallinginto the oil cellar here the enlarged portion of the shaft (13,) passesthrough the box (A,) said box forms a stufiing box ((7,) supplied with agland (E,) fitting closely therein and secured by the bolts (f f,), bymeans of said gland and stufling box the joint formed when the shaft(13,) enters the box (A,) is rlendered a perfect one and impervious torust.

It will be observed that by forming the axle without any collar thesimple brass box, (D,) is readily withdrawn from over the axle, throughthe opening covered by the plate (F,) and that by the simpleconstruction and arrangement of the parts of my 1mproved box, itsinterior and the bearing surface of the shaft are readily approachedwhen desired, for cleaning or other purpose, while by the use of thestufiing box and gland the oil is retained and the admissigii of dustinto the box rendered impossi e.

It will be readily seen that my box though possessing great advantagesover those now in use, is so simple in its construction that it is evenmore economical.

Having described the construction and operation of my improved box whatI claim as my invention is:

The combination of an ordinary gland and stuffing box with the journalbox of a rail road car, whereby the oil is retained and the admission ofdust rendered impossible, the whole constructed and arrangedsubstantially as and for the purpose specified.
